Im surprised they would call anyone out for getting onto that little rock though, you have to do more than that just to climb that mountain in CoP so that shouldn't be surprising O_o;
Having just had to run this again recently going through CoP, can confirm -did not miss-. Such janky movement sometimes. XD
Ran it a lot back in the day but boy did I forget everything.
There's also a ledge you can sit up on at the zoneline from dunes to Highlands, iirc. I remember not being able to get up as a taru but on a chocobo I could.
As well as a weird lamp next to a doorway (I think) in Al Zahbi? You glitch run over the ledge above it and drop down to stand on it.
Just sayin.. alot of time was spent waiting for besieged. >_>
Edit: The Dumb "Waiting for Besieged" Lamp glitch. You can also just get over the railing and walk to either side. It's relatively useless for anything ever. lol (Also i think it works with any of the ledges in that area)
